ATTORNEY UNI ED STATES PATENT OFFICE EDWARD LANDER HALL, OF NEW YORK, N. r.

CAMERA- I Brooklyn, in the county of Kings and tate.

of New York, have invented a new and Imroved Camera, of which the following is a 11, clear, and exact description.

The purpose of the invention is to provide a compact, sim 1e and inexpensive camera of the type in w oh the shutter is connected with the focusingmirror in such manner that when the mirror is brought to focusing osition theshutter will be carried out of the coal plane of the lens and whereby when the mirror is carried up to effect an exposure the shutter is automaticall carried to working position relative to the ens and is also automatically operated.

The invention consists in theanovel construction and combination of the several parts, aswill be hereinafter fully set forth, and pointed out in the claims. I I

Reference is to be had to the accompanying drawings, f0 a part of this specification, in which si ar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical section throu h the camera, the parts being shown by in lines in position for exposure and by dotted lines in position for focusing. Fig. 2 is a vertical transverse section taken practically on the line 2 2 of Fig. 3;..and Fig. 3 is a horizontal section through that portion of the camera-box in which the shutter is located, the section being taken practically on the line 3 3 of Fig. 2.

A represents a camera-box which is divided into a lens-compartment B and a view com artment or chamber C by means of a partition 12. The box is provided with the usual rear 0 ening 10 to receive a plateholder, and t 's opening 10 is surrounded by a frame 11 at the inner portion of the box. (Shown best in Fig. 1.)

The lens B is located (apposite an opening 14 in the partition 12, an a suitable o ening 14 is made in the front of the box or the outward passage of the lens, and this opening 14 when the box is not in use is closed by a 7 door 14".

The lens-board 13 is ad'ustably connected with the partition 12 by a ellows 15, and the lens-board is guided in its movement by up- Bpodflcatiom of Letters Patent.

per bars or plates 16, secured to its side ortions, and the said bars or lates have all g movement in housin 17, ocated within the camera-box at its si es, as is shown in Figs. 1 and 2 and rack bars-or plates 18 are secured to the lower portion of the said lensboard at its sides. These rack-bars have shding movement inhousin s 19. (Also shown in Figs. 1 and 2.) The teet of the rack-bars 18 engage with ginions 20, secured upon a shaft 21, operate at the exterior of the camera-box during the focusing operation.

A short partition 0 is located at the rear of the partition 12. .The artition 12 extends from side to side and omtop to bottom of the camera-box; but the artition C but reaches from side to side of the box. The lower end of this short rear partition 0 is qz'ovided with a covering 20", of felt or dar cloth, for a purpose to be hereinafter described.

An opening 22 is made in the up er'portion of the camera-box A, extendin i i-om the partition 0 to the rear of the sai box, and this opening is normally closed b .a hinged cover 23, preferably provided wit a mirror 24 upon its inner face. The said cover 23 is connected with the marginal portions of the opening 22 by a bellows 25, in which bellows a sight-opening 26 is made, the said opening being revented from accidentally closing when t e cover 23 is raised for focusing by means of a 8 ringoke 27, located within the bellows at t e sai opening 26. At the bottom portion of the s ace inclosed by the said cover 23 and the be] ows 25 a ground glass 28 p is secured.

A focusing-mirror D is located beneath the ground glass28, which mirror is set in a late 29, having a hinged connection 30 wit the upper portion of the framin 11 around the opening 10' for the plate-holder, as is shown in Fig. 1, and the said plate 29 is provided with a flange 29, extending upwardly from each side, as is shown b dotted lines in Fig. 1', which flanges when t e mirror D is in its upper position, or position for exposure, enter ooves in the sealing-strips 40, located at the sides of the box between the back and the partition 0, the lower edges of which sealing-strips have the same inclination as that of the mirror when in the upper position. (Shown in Fig. 1.)

loo

It will be understood that the sealingstrips are simply strips of wood or metal located in the rear chamber of the camerabox at each side, extending from the-rear of the artition C to the rear wall of the box the ower ed es of the strips bein inclined to correspon to the inclination of t e mirror D when said mirror is in an upper position, or

in a position for the exposure of a plate, and a space is made to intervene between the side wals of the camera-box and the sealingstrips to receive projectionsfi'om the mirrori'rame, to be-heremafter described, in order to make a li ht-tight connection at such points when a p ate is to be exposed.

A shutter E is attached t8 the plate 29 at its forward end by a hinge 31, and the said plate is provided with an upright strip 32, adapted to engage the front ower portion of the short ipartition 0 when the nnrror is in place to e of the mirror an engagement is effected against the covering 209 of the partition C, makin thereby a light-ti ht connection.

' A .bfilows 34 is secure to the mirror-supporting plate 29, the shutter E, and the framm 11 around the opening 10 for the plateho der, so that a perfect collapsible exposure-chamber E is. obtained, havin the shutter E at one end'and'the late to e exposed at the opposite end, prings 33 are attached to-the shutter E and tothe mirrorcarrying plate 29, which springs tend to hold the shutter in an upright positlon.

The shutter E 1s provided with pins 35, which extend out throu h its side surfaces. These pins when the bel ows is dropped and the mirror D is carried to focusing position eng V e with the inclinedu per faces of plates 36, w ich are secured tot e bottom ortion of the camera. These plates 36 are 'ghest -at their forward ends, so that when the mirror D is carried to focusilig position and the pins 35 of the shutter engage with the plates 36 the shutter is carried down sub-' stantiall parallel with the bottom of the ca'merafox, as isshown by dotted lines in Fig. 1. and-entirely out of the field of the lens B, at which time the'springs 33 are placed under tension. The movement of the shutter E is limited, preferably, by attaching a segmental arm 37 to the shutter at one of'its s1 es, which segmental arm is provided with a longitudinal slot 38, and the said slot 38 receives a pin. 39, which is secured to a side ed e of the mirror-carrying plate 29.

it may here be remarked that the upright I stri 32 of the mirror-carrying plate 29 exten s from side to side of the I camera and that the said plate-in its upper position en- 2 so as to prevent any possible leakage of liglitto the ex osure-chamber.

In .order that t e shutterE maybe conveniently set for time or for instantaneous work, a

cot anexposure, in which position the-box to a oint a pages with the sealing-strips 40, as shown indoor 39" is placed in the bottom of the box, as is shown m Fig. 1, which when opened admits of ready access to the shutter. The focusing-mirror D, the exposure-chamber E, and the shutter E are operated from the exterior of the camera-box 1n the followmg-manner:

A link 40 is pivoted'to one side of the focusin -mirror 'orits carrying-plate near the ivot o? the latter, asshown in Fig. 1. The

ink 40 is also pivoted to therear end of an arm 41, which arm extends along the inner si'deof the camera-box to-a point 1n advance I of the shutter E, where a downwardly-exten link 42 is pivoted to the said arm, and thelink 42 in its turn is pivoted to a second link '43, which latter hnk through the medium of a spindle 435 is connected with a crank 44 at the outside of the camera-box. Thelinks, 42 and 43 constitute a toggle, and

the arm 41 is pivoted to the box A at apoint 41" between its forward end and its. center, and a spring 40*, secured to the rear portion of the camera-box, has such engagement with the carrying-plate 29 of the focusingmirror D as to carryand hold'said late in the upper position. (Shown by full ines in TVhen the focusing-mirror is in its u per position, the strip 32 and that portion 0 the carrying-plate 29 below the partition 0 enpages with the material 20, covering the ower edge of the partition, and thus a ightti ht connection is made between the said p ate 29 and the said partition C.

When the mirror-carrying plate 29 is in its upper position, the links 42 and 43 are at an, angle to each other, as is shown-in Fig. 1; but when the crank .44 1s turned so as to bring the two links 42 and 43 in longitudinal alinement.

the mirror Dis carried to the lower position,

(shown by dotted linesin Fig. 1,);which: is the position for focusing, and the ins-35 of the shutter E, traveling on the ma ed surfaces of the plates36 at the bottom of the camera, will cause the shutterE to face down: ward and closely approach the bottomofi the camera, takin of the field o1 thelens. the same time accommodatfis itself'to the focusing position of the mirror.

' A tri latch 45 ismounted to slide inithe the said shutter entirely out;

The bellows 34 at rue camera-box, which trip-latch extends through acent to the forward edge of, the lin 42, as is shown in Fi 1, and

lug-mirror is in its lower or focusing position and the links 42 and..43 are straight and it is desired to bring the-mirror up to make an exposure it is simply necessary to push the eldin I 20 v the said trip-latch 45 is provided wit a head trip-finger inward by ressing the pushbutton 48' whereupon the sad 46 of the tripthe medium of a knob 52 at its outer end.-

The tri '-bar 51 is provided with a crank-arm 53, an a spring 54 is secured to said arm and to the inner face of the camera-box, as is particularly shown in Fig. 2, so as to hold the inner member of the said bar in a-horizontal position. When the focus has been obtained and the trip-latch 45 has been pressed inward to ermit the focusin -mirror to be carried to its up er position, shown by full lines in Fig. 1,) t e trip-finger 49 of the shutter E will engage with the inner member 50 of the trip-bar 51 and the said finger 49 will immediately operate the shutter.

When the shutter is set for time exposure, the trip-finger 49 of the shutter is operated by simply turning the trip-bar 51 until the finger 49 is pressed downward, whereupon the trip-bar'51 is released, and-its spring 53 will immediately restore the said bar to its normal positionthat is to say, the arm or inner member 50 of the trip-bar 51 will be so far above the lower end of the trip-finger 49 as to permit the same to rise far enough to operate the shutter to a closed position.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. In a camera, a box, a lens within the box, a bellows exposure-chamber having a hinged connection with the back of the box and located within the same, a tension device having a lifting influence upon the said chamber, a focusing-mirror constituting the up er rtion of the chamber, a spring-contro ed shutter hinged to the forward portion of the chamber, an automatic folding mechanism for the shutter, manually-operated devices for folding the said chamber, which devices cause the automatic folding mechanism to operate, and means for automatically operating the shutter when the said chamber is raised to normal position.-

2. In a camera, a box, a bellows exposurechamber, a focusing-mirror forming the upper portion of the chamber, a spring-controlled shutter having folding relation to the chamber, external means for controlling the movement of the chamber, internal means for folding the shutter face down out of the field of the lens when the chamber is folded and the mirror is brought to focusing .position, which means include guides from the shutter, having limited movement with reference to the upper ortion of the exposurechamber, inclined p anes on the bottom of the camera-box, and projections from the shutter which en a e the inclined planes when the focusinge lows is collapsed.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses.
